A piston cylinder device initially contains steam at 3.5 MPa, superheated by 5 C. steam loses heat to the surrounding and the piston moves down hitting a set of stops at which point the cylinder contains saturated liquid water. the cooling continues until the cylinder contains water at 200 C

(a)the initial temperature

(b)the enthalpy change per unit mass of the steam by the time the pistion first hits the stops.

(c)the internal energy change of the waterneon is compressed from 100 kpa and 20C to 500 kpa in an isothermal compressor.

(d)determine the change in the specific volume and specific enthalpy of neon caused by this compression
